Hi,
First of all let me say that GLPK and GNU Math Prog are great. I have been using it via Java and R.
However, I do have some enhancement suggestions:
- ordered sets: for example: set time ordered;
- access of elements:
- last(set_name)
- first(set_name)
For example:
set time ordered;
set time:= 1 2 3;
last(time) would return 3 and first(time) would return 1. This would make writing constraints much easier.
All the best,
Katharina
